7.2
Power supply
The STM32WBA65I-DK1 Discovery kit IoT node board is designed to be powered by a 5 V DC power supply. It is
possible to configure the Discovery board using a jumper on JP4 to use any of the following five sources for the
power supply: 5V_USB_STLK, 5V_VIN, 5V_EXT, 5V_USB_CHGR, and 5V_USB_MCU. The user must only
connect one source at a time.
A power supply unit or auxiliary equipment complying with EN 62368-1:2014+A11:2017 or its superseding
standard must power the product. It must also be a safety extralow voltage (SELV) with limited power capability.
7.2.1
5V_STLK
5V_STLK is a 5 V DC power with limitation from the STLINK-V3EC USB Type-C® connector (CN6). In this case, a
jumper must be set on [1‑2] to select the 5V_USB_STLK power source on the JP4 silkscreen (refer to Figure 9
below). This is the default setting. If the USB enumeration succeeds (as explained below), the 5V_STLK power is
enabled by asserting the T_PWR_EN signal (from STLINK-V3EC MCU). This pin is connected to a power
controller, which powers the board. This power controller also features a current limitation to protect the PC, in
case of a short circuit on the board or if the USB port cannot provide the necessary current.

5V_VIN
5V_VIN is the 7 to 12 V DC power from the ARDUINO® connector (CN9 pin 8) named VIN on the ARDUINO®
connector silkscreen (the extension connectors for ARDUINO® Uno shields or daughterboards). In this case, a
jumper must be set on [3‑4] to select the 5V_VIN power source on the JP4 silkscreen (refer to Figure 10 below).
In this case, the DC power can come from the power supply through the ARDUINO® battery shield (compatible
with the Adafruit® PowerBoost 500 shield).

In this case, a jumper must be set on [5‑6] to select the 5V_EXT on the JP4 silkscreen (refer to Figure 11).
A voltage source or auxiliary equipment compliant with EN 62368-1:2014+A11:2017 or its superseding standard
must power the product.

5V_USB_CHGR is the DC power charger connected to the USB STLINK (CN6). A jumper must be set on [7‑8] to
select the 5V_USB_CHARGER power source on the JP4 silkscreen. In this case, if the STM32WBA65I-DK1
Discovery board is powered by an external USB charger, the debug is not available. If a PC is connected instead
of the charger, the limitation is no longer effective and this might damage the PC.

Current measurement
The device has low-power features. It can be interesting to measure the current consumed by the
STM32WBA65RI on the discovery board. To do this measurement easily, there are two possibilities:
1. Measure the supply current of the SoC using an ammeter in place of the jumper (JP2). Refer to Figure 15
below.

2. Use an external power supply with current measurement capability. In this case, the jumper (JP2) must be
OFF and the supply must be connected to pin 1 of JP2 (refer to Figure 16). The supply voltage must be
between 1.8 and 3.3 V. The rest of the board is powered by any other supply on JP4.

3. If it is necessary to do power consumption measurement during debugging, STMicroelectronics has an
interesting solution. It is possible to use an STLINK-V3PWR. This product allows two sources of supply: a first
for the current measurement on the STM32WBA65RI, and a second source to supply the rest of the board
(LEDs). As in the previous case, the jumper (JP2) must be OFF, and the main supply (for current
measurement) connected to pin 1 of JP2 (refer to Figure 17). For the second source (+5V), it is necessary to
set JP4 OFF and connect this source to the top side (pin 10, 8, 6, 4, or 2 of JP4).
The supply voltage on JP2 must be 3V3.

ARDUINO® Uno V3 connector
CN8, CN9, CN10, and CN11 are female connectors (SMD component devices) compatible with the ARDUINO®
standard. Most shields designed for ARDUINO® can fit the STM32WBA65I-DK1 Discovery board.
The ARDUINO® connectors on the Discovery board support the ARDUINO® Uno V3.
The I/Os of this STM32WBA65RIV7 microcontroller are 5 V tolerant and there are no issues with ARDUINO® Uno
compatibility.
The connector provides the PTA signal for Wi‑Fi® coexistence and audio for use with DSP.
The normal MCU I/Os on the ARDUINO® must be programmed in high impedance when using PTA or audio on
the ARDUINO® connector to avoid short circuits on the I/Os.

On the main board sticker, the first line provides the product order code, and the second line the product
identification.
On all board stickers, the line formatted as “MBxxxx-Variant-yzz” shows the board reference “MBxxxx”, the
mounting variant “Variant” when several exist (optional), the PCB revision “y”, and the assembly revision “zz”, for
example B01. The other line shows the board serial number used for traceability.
Products and parts labeled as “ES” or “E” are not yet qualified or feature devices that are not yet qualified.
STMicroelectronics disclaims any responsibility for consequences arising from their use. Under no circumstances
will STMicroelectronics be liable for the customer's use of these engineering samples. Before deciding to use
these engineering samples for qualification activities, contact STMicroelectronics' quality department.

•
•
On the targeted STM32 that is soldered on the board (for an illustration of STM32 marking, refer to the
STM32 datasheet Package information paragraph at the www.st.com website).
Next to the ordering part number of the evaluation tool that is stuck, or silk-screen printed on the board.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a “U” marking option at the end of the standard part number
and is not available for sales.
To use the same commercial stack in their applications, the developers might need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.
